The development of nuclear weapons during the Manhattan Project is one of the most significant scientific events of the twentieth century. This revised and updated 3rd edition explores the challenges that faced the scientists and engineers of the Manhattan Project. It gives a clear introduction to fission weapons at the level of an upper-year undergraduate physics student by examining the details of nuclear reactions, their energy release, analytic and numerical models of the fission process, how critical masses can be estimated, how fissile materials are produced, and what factors complicate bomb design. An extensive list of references and a number of exercises for self-study are included. Links are given to several freely-available spread sheets which users can use to run many of the calculations for themselves.

The development of nuclear weapons by the Manhattan Project during World War II was one of the most dramatic scientific/technological episodes in human history. This book, prepared by a recognized expert on the Manhattan Project, offers a concise survey of the essential physics concepts underlying fission weapons. The text describes the energetics and timescales of fast-neutron chain reactions, why only certain isotopes of uranium and plutonium are suitable for use in fission weapons, how critical mass and bomb yield can be estimated, how the efficiency of nuclear weapons can be enhanced, how the fissile forms of uranium and plutonium were obtained, some of the design details of the 'Little Boy' and 'Fat Man' bombs, and some of the thermal, shock, and radiation effects of nuclear weapons. Calculation exercises are provided, and a Bibliography lists authoritative print and online sources of information for readers who wish to pursue more detailed study of this fascinating topic.

In August 1945, two US Army Air Force B-29 bombers each dropped single “atomic bombs” on the Japanese cities of Hiroshima and Nagasaki. Little Boy and Fat Man each exploded with energies equivalent to more than 10,000 tons of conventional explosive. Just seven years later, in October 1952, the Ivy Mike test saw the detonation of America’s first full-scale thermonuclear weapon that achieved a yield over 400 times as much as Little Boy and Fat Man. The invention of nuclear weapons was one of the most stunning scientific and technological developments of the 20th century. Carried out under the auspices of the United States Army’s Manhattan Project, this development had profound immediate and long-term impacts: the bombings of Hiroshima and Nagasaki helped bring World War II to a close, but set the stage for the Cold War, nuclear proliferation, and fear of nuclear annihilation and terrorism. This volume, prepared by an acknowledged expert on the Manhattan Project, gives a concise, fast-paced account of all major aspects of the project at a level accessible to an undergraduate college or advanced high-school student familiar with some basic concepts of energy, atomic structure, and isotopes. The text describes the underlying scientific discoveries that made nuclear weapons possible, how the project was organized, the daunting challenges faced and overcome in obtaining fissile uranium and plutonium and in designing workable bombs, the dramatic Trinity test carried out in the desert of southern New Mexico in July 1945, and the bombings of Hiroshima and Nagasaki. The final chapter surveys current worldwide nuclear weapons deployments, and a bibliography lists sources of published and online information along with numerous links.

The development of atomic bombs under the auspices of the U. S. Army’s Manhattan Project during World War II is considered to be the outstanding news story of the twentieth century. In this book, a physicist and expert on the history of the Project presents a comprehensive overview of this momentous achievement. The first three chapters cover the history of nuclear physics from the discovery of radioactivity to the discovery of fission, and would be ideal for instructors of a sophomore-level “Modern Physics” course. Student-level exercises at the ends of the chapters are accompanied by answers. Chapter 7 covers the physics of first-generation fission weapons at a similar level, again accompanied by exercises and answers. For the interested layman and for non-science students and instructors, the book includes extensive qualitative material on the history, organization, implementation, and results of the Manhattan Project and the Hiroshima and Nagasaki bombing missions. The reader also learns about the legacy of the Project as reflected in the current world stockpiles of nuclear weapons.

"Authors Ruth H. Howes and Caroline L. Herzenberg discuss the various scientific problems the women helped to solve as well as the discrimination they faced in their work. Their abrupt recruitment for the war effort and anecdotes of everyday life in the clandestine, improvised communities, what happened to the women after the war, and their present attitudes toward the work they did on the bomb are also included."--Jacket.

2004 marked the centennial of the birth of J Robert Oppenheimer, and brought historians and scholars, former students, nuclear physicists, and politicians together to celebrate this event. Oppenheimer's life and work became central to 20th century history as he spearheaded the development of the atomic bomb that ended World War II. This book provides a spectrum of interpretations of Oppenheimer's life and scientific achievements. It approaches the extraordinary scientist and teacher from many perspectives, chronicling the years from his boyhood through his role as director of the Los Alamos National Laboratory and afterwards. The book also discusses Oppenheimer's connection to New Mexico, which hosted two of the Manhattan Project's most crucial sites, and addresses his lasting impact on contemporary science, international politics, and the postwar age.

During World War II, nations raced to construct the worldOCOs first nuclear weapon that would determine the future of the world. The Manhattan Project, one of the most significant achievements of the 20th century, was the culmination of AmericaOCOs war effort. Today, although the issue of nuclear weapons frequently dominates world politics, few are aware of the history behind its development. Part I of this book, comprised of papers from the Atomic Heritage FoundationOCOs Symposium on the Manhattan Project, recounts the history of this remarkable effort and reflects upon its legacy. Most of the original structures of the Manhattan Project have been inaccessible to the public and in recent years, have been stripped of their equipment and slated for demolition. Part II proposes a strategy for preserving these historical artifacts for the public and future generations."

Arkansas, 18. September 1980, abends: Bei Routinearbeiten an einer gefechtsbereiten Titan-II-Rakete rutscht einem Arbeiter ein Schraubenschlüssel aus der Hand. »O Mann, das ist nicht gut”, ist sein erster Gedanke. Das Missgeschick führt zu einer Kettenreaktion, der größte je gebaute Atomsprengkopf droht zu explodieren ... Weltweit sind Tausende von Atomsprengköpfen stationiert. Viele von ihnen werden rund um die Uhr gefechtsbereit gehalten, damit sie innerhalb einer Minute starten und eine unvorstellbare Verwüstung anrichten können. Was das für die Soldaten in den unterirdischen Bunkern heißt und welche Gefahren von den scharfen Atomwaffen ausgehen, ist uns kaum bewusst. Der Journalist und Bestseller-Autor Eric Schlosser deckt in diesem zeithistorischen Thriller auf der Grundlage von geheimen Unterlagen des Verteidigungsministeriums und Interviews mit Augenzeugen einen dramatischen Unfall in einem Atomwaffensilo der USA auf, der um ein Haar mehrere amerikanische Großstädte vernichtet hätte. In diesen Krimi einer am Ende gerade noch gelungenen Rettung flicht er die Geschichte der amerikanischen Atomrüstung ein. Er erzählt, wie Raketen und Sprengköpfe rund um die Uhr abschussbereit gehalten werden und wie die Menschen ticken, die ihr Leben für die Sicherheit der Massenvernichtungswaffen einsetzen. Eine spektakuläre Geschichte des Kalten Krieges und der Atomrüstung «von unten»: aus der Sicht der Soldaten in den Silos, die mit einem falschen Handgriff die Apokalypse auslösen können. «Atemberaubend, ... mitreißend ... Eric Schlosser verbindet profunde Informationen mit der Erzählung haarsträubender Details zu zahlreichen Unfällen und zeigt, dass auch die besten Kontrollsysteme nicht menschlichen Fehlern, Missgeschicken und der wachsenden technologischen Komplexität gewachsen sind.» Publisher’s Weekly »Ebenso anschaulich wie erschütternd ... Eine umfassende und beunruhigende Untersuchung über die Illusion der Sicherheit von Atomwaffen.” Kirkus Reviews «Die weltweiten Atwomwaffenarsenale sind nicht so sicher, wie sie sein sollten – das ist die Botschaft dieses faszinierenden und aufwühlenden Buches.» Lee H. Hamilton, ehemaliger Kongress-Abgeordneter der USA und Co-Vorsitzender der Blue Ribbon Commission on America’s Nuclear Future
